The ISA TRAQ program is voluntary and developed to train and assess an individual’s degree of knowledge and skill in a specialized field of arboriculture. When a professional earns the ISA TRAQ credential, they should be recognized by their peers and the public as a tree care professional who has specialized knowledge and skills in tree risk assessment. To earn the qualification, applicants must meet eligibility requirements, complete a training course, and pass both a comprehensive written assessment and a performance-based assessment. To maintain the qualification, current credential holders must retrain and retest every five years.
